iPod and MP3 Player Help

My Apple iPhone 6 Plus seems to be filling up even though I haven’t added any new apps, songs or movies. I take a lot of photos, but I delete them once I’ve done a backup. What’s the fix to recover disk space on my iOS device?

I’m trying to cancel my monthly subscription to Netflix but when I go to the site it says I have to cancel it within iTunes on my iPad or iPhone. How do I find my Netflix subscription account info on my iPhone??

My son gave me his old Apple iPod Nano (the rectangular one with the wheel controller) and when I plug it into my Windows 7 system, it just complains that it’s a Mac format device and won’t let me do anything other than reformat it. How can I use it as an iPod??

I’ve given my kids my old iPod Nano and they’ve been taking all sorts of videos with it. Now they tell me that some of them are good and they want to upload them to YouTube. Except while I know how to get an iPhone video on the site [see my tutorial: Upload iPhone videos to YouTube for details -Dave] I have no idea how to get the video off the iPod and onto my iMac.
